GL_StClair_Detroit_River 2019 ESI: Threatened and Endangered Plant Habitats

Vector polygons represent threatened and endangered plant distributions in the St. Clair and Detroit River system. This data characterizes coastal environments by their sensitivity to oil spills, covering shoreline habitats, biological resources, and human-use resources. The dataset was published by the National Oceanic and Atmospheric Administration and last updated in March 2026.

Use Cases

• Modeling oil spill impact sensitivity based on habitat and species data.
• Mapping distributions of threatened and endangered plants for conservation planning.
• Analyzing coastal resource vulnerability by integrating biological, habitat, and human-use layers.

Strengths

• Data is part of a standardized Environmental Sensitivity Index (ESI) framework for oil spill response.
• Includes associated tables with species-specific abundance, seasonality, and life history information.
• Covers a specific geographic system including Lake Huron, St. Clair River, Lake St. Clair, Detroit River, and Lake Erie.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is provided in PDF format, which may not be ideal for direct spatial analysis.
